Cooler Master has unveiled its 300 kW AALC (Air-Assisted Liquid Cooling) In-Row CDU, offering up to 450 kW of peak cooling capacity for AI infrastructure including GB200 and GB300 NVL72 racks, with compatibility for future VR200 systems.
Key points:
- No facility rebuild needed: liquid-to-air design deploys in existing data centers lacking liquid cooling infrastructure
- Dual V-pattern radiators plus eight hot-swappable fans per rack, 3-5°C approach temperature
- Redundancy across pumps (2+1), fans (2×7+1), and filters (1+1); UPS support for 90 seconds during outages
- Field-replaceable units with quick disconnects for pumps, fans, filters, CRPS, and BBU
- Sub-90 dBA noise, cross-rack manifold integration, real-time self-diagnostics and monitoring
